2.  Name given because they don’t interact with
“common” elements. However, some have recently
been discovered to interact with other elements
 Colorless, odorless, and tasteless
 Full valence electron shells (making forming
compounds difficult)
 Very low boiling and melting points
 Have many different applications

3.  Comes from Greek helios meaning ‘the sun’
 Emits purple-orange light
 Second lightest and second most abundant
element in the universe.
 Lowest boiling and melting point of any
element.
 Used in cryogenics, flight, and filling balloons.
 The speed of sound in helium is 3x of that in
regular air, making your voice sound higher
than normal when inhaled.

4.  Means ‘new’ in Greek
 Most intense light discharge of all
noble gases.
 Emits bright red color
 Widely used in signs and lights.
 Once used to make television tubes.

5.  Comes from Greek argos meaning lazy,
due to not reacting at all with other
elements
 Emits blue-green light
 Third most common element in Earth’s
atmosphere
 Used in arc welding, lighting, and scuba
diving equipment

6.  Comes from Greek kryptos meaning
‘hidden’
 Emits light orange-white color
 Length of a meter was once based on
light emitted from excited Krypton
atoms
 Used in many different lights and lasers
 Considered a non-toxic asphyxiant,
large quantities will replace oxygen

7.  Means ‘stranger’ in Greek
 Emits a bright blue-lavender glow
 Used in plasma TVs, lasers, and as an
anesthetic
 Speed of sound is lower, causing the opposite
effect of helium
 Considered safe but still risky, as it has the
potential to cause asphyxiation if too much is
inhaled

8.  Named after radium, as it is radioactive
 Emits phosphorescent (glow in the dark)
yellow only when cooled to extreme
temperatures
 Heaviest of all noble gases and one of the
heaviest gases at room temperature
 Once used for medical purposes, stopped
when revealed it was radioactive
 Is a carcinogenic gas and considered a public
health risk

9.  Helium- 1s2
 Neon- [He] 2s2 2p6
 Argon- [Ne] 3s2 3p6
 Krypton- [Ar] 3d10 4s2 4p6
 Xenon- [Kr] 4d10 5s2 5p6
 Radon- [Xe] 4f14 5d10 6s2 6p6
